Can't see Mac network with JFileChooser

Greetings
I am using a standard JFileChooser to select files and directories in my application running on MacOSX Snow Leopard. My problem is that I can't see my network using JFileChooser. I can see all the other Macs on my network using Finder or a standard Mac file browser but not on JFileChooser. I suspect I am missing something really simple but at the moment I am at a loss.
Any suggestions would be most appreciated.
Regards

Hi,
I also have the same problem.
My belkin wirelss router is set to channel 13, therefore my macbook cannot see this network when it search's, for the above reasons.
However unlike the situation above I am unable to change from channel 13 as we have discovered in the past that this is the only channel that is not in use by other networks around our area. The rest gave us interferance troubles.
I have a number of windows laptops in the house and there is a setting that you can change so the laptop will search for channel 13. I was wondering if anyone is aware of a setting on the macbook that will make the airport card search for 1 - 13 not just channels 1 - 10 as it is now.
I thought I would add this question to this topic as it is very similar. I hope I was correct in doing so.
Thanks,

Can't see wireless network with Windows Vista

I have the Airport Extreme N and two PCs, one with W XP and one with W Vista. Everything works fine with the XP PC. On the Vista PC, I can connect to the network with LAN, but I can’t see the wireless network.
The W Vista PC can identify other networks around the block, so the Broadcom 802.11g network adapter seems to work fine. The wireless runs on channel 13, which is OK for the XP PC. I have installed the latest update for the Airport Extreme.
Any suggestions to what I can do to get the W Vista PC working on wireless?
Best, Kasper

Airport + Wired Network - Can't see Wired Network with new Ethernet Switch.

I have an Airport Exteme Wireless network work in my home with a base station and one base station as a WDS. I had an old Linksys wired router that I used as an etherent hub for my wired computers. It died the other day.
Since I figured I already have a router with Airport, I went out and bought a NetGear 5 port gigabit switch to hook the wired part of my network back up. Since I have done this, I can see all the computers on the wireless Macs, but cannot see the network at all on the wired Macs.
My configuration is:
Cable modem -- > Airport (WAN) --> Netgear wired etheret switch (LAN).
I'm checking the "distribute IP addresses" from the airport. All the compters can access the internet, but my wired Macs can't communicate on the network. I'm darned but I can't seem to figure this out.
For all you networking gurus out there, what am I doing wrong? I could have bought another wired router, but it seems I shouldn't have to since my Airport should be able to perform the router function to all computers but hooking it to the ethernet switch.
Any suggestions or help would be most appreciated.
Thanks in advance,
Scotty D
Sorry, I posted this on the AirPort Express discussions by mistake. Apologies, but it belongs here.

You are able to ping the printer from the wireless computer but not from wired computer.
Open router setup page. Go to wireless tab and click on Advanced wireless settings sub tab.
Make sure that AP Isolation is disabled on your router.
Also check the firewall settings on your wired computer. If there is any firewall or Anti virus installed on your wired computer then disable it and try to ping the printer IP address.

MacBook Pro can't see Airport network but three other macs in house can

Very strange. I can connect my three iMacs (G3, G5 PowerPC and G5 Intel) to my Airport Extreme Network, but my MacBook Pro can no longer see the Network, and Airport utility (from MacBook Pro) cannot see the Airport base station (although other macs' Airport Utility can no problem). My MacBook pro can see 4 other networks (my neighbours' networks). Doesn't seem to be a problem with my MacBook Pro airport card as I can connect to the (non-Mac) wireless network at work with no problem. Am really confused (not the first time)!
Installed the latest Airport Extreme firmware last week, which was the start of the problem, as I then lost the ability to connect to my Virgin Media Broadband digital TV box, necessitating Virgin engineer visiting at weekend to connect a cable modem to the cable tv box, to which the Airport Extreme station is now attached. Had problems connecting my MacBook Pro last night, but eventually managed it. All other macs connect seamlessly. Am stumped.

I'm troubleshooting a friend's MacBook (Model ID: MacBook4,1) that is having serious Airport problems. This machine's Airport can't see ANY available networks. Sitting right next to my MacBook (identical model), hers is blind while mine can see several open and locked networks including my own Airport base station. If I choose to "Join Other Network..." and enter the network name and password for my network, her machine almost immediately gives me a "Connection timed out" error. It doesn't matter where her MacBook is, it can't see any networks anywhere.
This is a new problem as her Airport was working fine for the first few months. I've just finished making sure all software updates have been applied so she's now running the latest-greatest, but still no Airport.
This sounds similar to the problems other folks here are describing so I figured I'd add my voice to the chorus. I guess I'll take her machine down to the local Apple store this afternoon and see if they have any ideas. At this point I wouldn't be surprised if her Airport card was fried.

I HAVE A MAC NETWORK WITH A HP LASER-JET AND EVERYTHING IS WORKING FINE. I ALSO HAVE A WINDOWS BASED MACHINE THAT I WOULD LIKE TO PRINT TO AS WELL. HOW CAN I ACCOMPLISH THIS?

I HAVE A MAC NETWORK WITH A HP1200 LASER-JET AND EVERYTHING IS WORKING FINE. THE PRINTER IS CONNECTED DIRECTLY WITH ONE OF MY MAC-MINI"S. I NOW HAVE A WINDOWS BASED PC AND WOULD LIKE TO PRINT TO IT AS WELL.. HOW CAN I DO THIS?

Make sure that you Printer Sharing enabled on the Mac Mini. System Preferences > Sharing > Printer Sharing
Do the same on the PC
On the PC, try downloading and installing Bonjour Print Services for Windows v2.0.2
Run the application on the PC to see if it will discover your printer and install the printer.

Installed OSx Lion. Can't see my network user on launch

Hello,
installed OSx Lion a few hours ago but on OSx launch I can't see my network user anymore.
Network user was appearing properly on Leopard.
Please help as I can't get access to our company network anymore.
Thanks!

I figured out the answer. unfortunately, the Belkin router I have does not support a HDD formatted in Mac OS. I guess I have to decide whether to stay with FAT32 for my netweork drive or get a new router...

Can't see a network (Netgear router) I know exists

I've in the process of relocating and am in temporary accomodation without broadband, but have been lucky enough to get to know my neighbour who is running a wireless network next door on a Netgear router (not sure which model) and has offerred to let me connect via that.
However, now that I'm home and trying to do so I can't see the network. I'd guess that the router is only about 50 feet away through a couple of walls, so I wouldn't have thought that would be a problem. There is also supposed to be another wireless network running in the building, but I can not see that one either.
Before I moved I used a Netgear DG834G wireless router myself with my Airport Extreme-enabled Pwerbook, and I can't remember having trouble seeing the netwrok when setting that up (though it was a couple of years ago so memory may be fuzzy).
Does anyone know how I can scan for non-Airport Base Station networks?
Or do I just need to go back to my neighbour and get the IP Address to configure manually?

If your neighbor's wireless router isn't visible to your Mac, getting and IP address and configuring manually won't get you connected. Two things I suggest you do:
1. verify with your neighbor that his router is not configured with "SSID broadcast disabled", thus rendering his router invisible
2. see if your Powerbook gets a signal when located in your neighbor's apartment. Fifty feet and a couple of wall could indeed be beyond usable range.

Can't see wifi network

Today I got a wimax modem with built in wifi (greenpacket DX230). There is no customization of the device at all. The SSID and password are already printed on the device and are supposed to work without setup. However, I cannot see the network from my macbook running snow leopard, even if I am right beside the device. I have checked several PCs and they can all see the network, and my iPods can also see the network. I have yet to try another mac (will try tomorrow).
Does anyone know why this would be? I thought wifi was a standard and that there is no deviation from it? Why would my ipods be able to see the network but not the macbook? Kismac doesn't even show the network

It might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort menu bar item to turn AirPort off, then on again.
2) Try to select your Wi-Fi network from the AirPort menu.
3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease".
6) In the folder /Library/Preferences ( not <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
They may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

How can I see shared pc with firewall set to allow only essential services?

How can I see shared pc with firewall set to allow only essential services?
So far if I set it as above then shared does not show up? I have to set the firewall to set access to specific applications and services to get access to my windows based hard drive.

Ok I solved it myself. Not an ideal solution as I have to connect it manually each time but it will do... Unless anyone has a way to have it auto connect when I start the mac.

Can´t see my Networks adapters in the Device manager!

Help!
I´m using Yoga 2 pro/windows 8.1
I can´t see the Networks adapter in the Device manager?!
(and no internet/WIFI connection is not working any more)
I´ve tried to install the latest Wireless Driver from lenovos homepage but it there is still problems. The laptop still can´t find any network adapter and the wifi connection doesn´t work, as it did last week!
Any one who has the same exeperience/or knew how to deal with these kind of issues?
/Rasmus

hi Rasmus,
Can you try these steps:
1. Check if you have a Network Controller entry in the Device Manager and follow this guide to get the hardware ID and on how identify the device.
2. If there's no Network Controller entry in the Device Manager, then it's possible that the Wi-Fi card might have been disabled.
Things to try:
- Boot into the BIOS either by pressing Fn+F2 on boot-up, the OneKey Recovery button, or via the UEFI Firmare Settings.
- In the BIOS, navigate to the Configuration tab and disable the Wireless setting hit Fn+F10 to Save and Exit then shut off the machine.
- Boot back into the BIOS and enable the Wireless setting then hit Fn+F10 to Save and Exit and observe if you can now detect wireless networks.
Let me know how it goes.
Regards

IPhone Can not see home network

Ok, I have read a lot of strings about Wii issues and I have tried the following:
- Unplugged (rebooted) my cable modem
- Unplugged (rebooted) my Airport Extreme
- Rebooted my iPhone multiple times
- Turned on and off the Airplane Mode to re-search for WiFi connections.
- Searched manually for the connection (typing in name and password)
- Turned off the WAP/WAP2 Personal security
but nothing seems to work. I can not view my home network on my WiFi.
I can see all my neighbors networks and the phone works great on free networks around town but my home network will not show up.
My home network does work on my laptop though.
Any thoughts?

Nathan:
Great suggestion. I changed it to 802.11 n (with b/c compatability) and I can now see the network on my iphone and I can log in (I think).
I chose the network from the list and put in the password. The first couple of times it did not take but the 3rd or 4th time it seemed to log on. If I go to Settings and look in the Wi-Fi area it has my network name as the network it is logged into but...
There is no WiFi symbol on the top bar of the phone (only an E, for the Edge network) and when I chose any application (Safari, YouTube, etc.) it only accesses through the Edge network.
Any other thoughts?

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.

IPhone 4S - iOS 6 - can't see WiFi networks

I have a strange problem with my iPhone. It's a locked iPhone, bought from Vodafone from my country. I use it locked and un-jailbreaked. I went in France for 2 weeks where i had my Roaming active, but i didn't used cellular data, only WiFi. Now, back home in my country, it seems that i can't see wireless networks. I tried to reinstall, update to the last firmware, it seems that wireless appear for 1 second when at first start, then it disappears and i can't see no more WiFi networks in list, tho there are like 10 networks around me.
Any ideas? Or someone else had the same issue?
Thanks,
Nick

i went to Vodafone. They said they will replace it. It seems like a manufacturing defect.

Can I extend a network with an AirPort Extreme Base Station Rather than with an Express?

Topic title pretty well sums up the question.
I have a TimeCapsule Base Station with two Expresses for extending the network through the house.
We're doing a 3 room addition, and there is not a convenient place to put an Express in a wall outlet in the middle room of the addition, but there's a perfect place to put an Extreme on top of a piece of furniture.
So, can the Extreme act as an "extender" only, in lieu of using an Express?

Hiya.
You can absolutely extend a network with an Extreme. I've got a 5th gen. Extreme extending a network created with a 3rd gen. Time Capsule. On the Extreme, you'll have the option to allow (or not) WiFi clients. I recommend having all units updated to the current firmware (7.6.1 as of this writing). Note that extending doesn't work in daisy-chain fashion, meaning that your Expresses or Extremes will each connect to and extend from the TC. As such, you'll want the TC to be in as central a location as possible to offer the best coverage.

Can I extend a network with AE, then plug into it?

i have checked but can't seem to answer this exact question:
i have a time capsule and my G5 tower is plugged in using ethernet (no wifi card). I also have a MBP. i am moving my G5 one floor down where there is no ethernet plug, but the wife reaches.
can i extend the network with an AE and then PLUG the G5 into the AE? or will i need a wifi card?
thanks in advance
keith

You would use AirPort Utility to first check the settings on the Time Capsule
AirPort Utility - Manual Setup
Click the Wireless tab below the row of icons
Make sure there is a check mark next to "Allow this network to be extended". Otherwise, things won't work.
Note the exact Security setting you are using for use with the AirPort Express
Use AirPort Utility the same way for the Express
Click the Base Station tab to name the device, assign password, adjust Time, etc
Click the Wireless tab:
Wireless Mode = Extend a wireless network
Wireless Network Name = Same name as the Time Capsule network
Check mark next to Allow Wireless Clients
Wireless Security = Same setting as the Time Capsule
Wireless Password = Same password as the Time Capsule
Confirm Password
Update to save changes. You should have green light in 30-40 seconds and the ethernet port will be active.
